- THREE WAY DOOR; LOCK;

Application filed March 19,1926. Serial No. 95,963.;

This invention relates to door locks,- and more: particularlyto, aidoorlock which is provided with bar means interconnected with and operableby,a conventional type of ,mortised lock forsecurin'ga door in, acasement therefor, by extending the said bar.

means ,into thev doorrcasement-ata fixed pointgon a plurality of.thedoor edges comprising in conjuction; with. the latch and lockingbolt of. the door lock. The principal-object of the inventionis toprovide a. door v with: looking bar, 7 means operatively associatediwithamortlsed type; of door lock,

which provides a,pluralit, iofhbarilocking 1 points aboutthemectangularside edges of, thedoor, in addition, to the locking, mecha-H nismcomprising the. lock and said locking,

bar means:s multaneously operable with the saidndoor lockyupontheinsertionnof the usual, latch key in i said lock.

Another object of the invention is to provide a door, and casementtherefor, with locking means whereby thetdoor-will be securelylockedin.the casementtherefor,,1 and which cannot be easilylforcedopenizorre moved, out. ofv the casement by removing the hinges from thedoor or forcing the door otherwise. 7

Other objects of the invention will appear in the following detaildescription, and in the accompanying drawings, wherein:

Figure 1--is an elevational view of a door and casement therefor partlyin section, showing the locking elements as applied.

Figure 2-is a cross section through the lock on theiline 2-2 of Figure1.

Figure 3is a detail view illustrating the mannerof connectin the lockingbars to the studs positioned in the lock.

Referring more particularly to the drawing, the invention comprises acasement 10 and a door 11 therefor, provided in the usual mannenwith amortised lock 12 of conventional design with a key-operated bolt 13 forprojection into a bolt plate 14 usually provided in a casement edge.Operably associated with and in the interior of the mortised lock 12,are a pair of studs 15 and 16 vertically disposed therein, with theupper stud 15 having its lower end threadably attached to a flat spring17, comprising a part of the lock mechanism, and said stud 15 projectingthrough the upper side 18 of the mortised lock casing 19. The stud 16 issimilarly attached in the lower portion of the lock casing 19 to aspring 20 suitably 'ingbar's 30 and anchored in the casing19. The saidstuds 15 and'16 are positioned in the interior of the, 1001112, andnormally extend flush with the upper side 18 and lowerside 22 ,of thecasing 19. In addition to the recess-22, the door 11 is further providedwith a pair of vertical bores-24 and 25, the upper bore 24extending fromthe top edge 26 of the door 11, and? downwardly through thedoor andterminating in the recess 23, The lower bore 25 extends from therecess23, .in a

vertical manner through the entire lower portionzof the door'll andterminates adjacent the lower door edge 33 of the door 11; Said boresadapted toreceive a pair of lock;

with the, upper and-lower edges of thedoor 31, normally positioned flush4 and into the recesses 22, and 23,'fo' r threaded connection, to theupperand lower protruding ends of the studs 15 and-16, which arepositioned in the lock casing-:19. The door opening jamb of the casement10 has it's in: ner upper and lo'wer'edges 32 and 33 suit-ably recessed,as. at 34; Said recess placed in central, alignment with the lockingbars 3Q and 31, and extended to receive theends 35 and 36 of thelockingbars 30 and 31', upon the operation of the. look, from unlockedinto locked position.

In order to actuate the locking bars 30 and 31, and the studs 15 and 16therefor, the in-, terior mechanism of the mortised lock 12, has a lever37 and heel 38 formed thereon, pivoted in the casing 19 of the lock 12,and to one side of the key-actuated locking bolt 13. Said heel. 38extending to the rear end of the locking bolt 13 and adapted to beactuated by the key for the lock, simultaneously with the bolt 13. Thepivoted lever 37 is also provided on its top edge with an upwardlyprojecting lug 40 for engaging the underside of the flat spring 17 uponthe upward move ment of the heel 38 and the lever 37. The bottom edge ofthe bolt 13 is likewise provided with a depending lug 11 for engagingagainst the top surface of the fiat spring 20,

upon the outward movement of the bolt 13 of the locking bolt 13 alsocauses the lugs 40 and 41 to engage the springs 17 and 20, which in turnactuate the studs 15 and 16, carrying the locking bars and 31, andproject the ends and 36 of the said bars into the recess 34, provided inthe upper and lower edges of the easement 10 simultaneously with theentering of the outer end of the locking bolt 13 into the latch platelat provided therefor, and secured to the edge 37 otthe casement 10, inthe usual manner.

The lug tl holds the spring 20, and the bar 30 in a depressed or lockedposition, when the bolt 39 is extended, while the lug 40 on the lever 37engages the spring 17 for raising the said spring and the locking bar 31into locked position. and in order to maintain the bar 31 in this lockedposition, the lever 37 has a laterally projecting shoulder 40' extendinginwardly over the top edge of the bolt 13 for engagement of theunderside of the said shoulder on the heel 42 provided on the topsurface of the bolt 13, in order to hold the lever 37 in raised positionagainst the spring 17, when the bolt 13 has been extended by the key forthe lock 12.

Upon the return of the bolt 13 into normal unlocked position, the lever37 will drop into-normal position and release the spring 17,-stud 15 andbar 31 therefor, and at the same-time, the spring 20 will be released tomove under its own tension l'ipwardly. and thereby raise the stud 15 andthe bar 30, out of locked )osition,

vWhile have shown and described one practical embodiment of myinvention, it

is to be understood. that Ido notlimit myself to the exact constructionas set forth,

but consider myself at liberty to make such changes and modifications,as fairly fall within the scope of the appended claim.

lVhat I claim is:

In a three-way door lock, the combination with a keeper plate for fixedattachment to the jamb of a door opening, of a lock casing for mortisedattachment to the edge of the door, a key operable bolt operativelymounted in the casing and adapted to engage with the keeper plate,vertical bolts mounted in the lock casing with very remote extremitiespositioned to penetrate into the upper and lower jambs of said dooropening, yicldablc means to which the adjacent ends of said verticalbolts are connected to retain the remote ends thereof frompenetrationinto said upper and lower jamhs, and gravity lever pivoted insaid casing and having a heel in the path of the wing car ried by thekey for the purpose of actuating the lever, said lever having a laterallug overlying the key operated liolt and provid ed with means engagingunder the yicldable means of one of the vertical bolts for actuating itwhen the lever is tilted, the key operated bolt having means to rideunder the lateral lug when the lever is tilted. and means on the loweredge of the key operated bolt for operating against the yieldable meansof the other vertical bolt for actuating the latter into the lower jambnIn testimony whereof I aflix my signature.
